I must be getting better at programming…

… because I got this one without even having to read the alt text.

The alt text read “If androids someday DO dream of electric sheep, don’t forget to declare sheepCount as a long int.”

If you think that’s terribly unfunny, try this site.  Let me know if it’s more to your tastes.

Leap Year Mathematics

February 29, 2008

So this isn’t DIRECTLY technology-related, but if you’re a programmer or math person, you will probably appreciate this. 

Assuming you get paid each Friday, only once every 28 years do you get a leap year like this one – a leap year in which there are 5 paydays in February.

Normally, years ending in 00 can’t be leap years – this would result in one 56-year gap between 5-Friday Februaries every 800 years. However, any year ending in 00 IS a leap year when divisible by 400.

If my algorithm is solid, every year which would result in a 56-year gap seems that it would fall on a year divisible by 400. So it seems there will never be a 56-year gap between 5-Friday Februaries. Correct me if that math is wrong; I’m just musing now. =)

Enjoy your 5-payday month (or 3 if you’re on biweekly).
